Specification of Letters Patent.

Patented Mar. 112, 1-918.

Application tiled September 11, 1914. Serial No. 861,196.

To all whom it may concern:

Be it known that 1, JOHN P. Wnrs, a citizen of the United States, residing at Nyack,

Improvements in Sewing-Machines, of which the following is a specification.

This invention relates to that class of sewing machines particularly adapted for sewing filled bags, the sewing mechanism being so mounted that the main driving shaft is in a vertical position while the needle bar operates horizontally so that the stitching position of the bag is at the end of the machine with no projecting parts of the machine extending below the stitch line to interfere with the filled bags as they are passed to and from the sewing machine by means of a conveyer commonly used for this purpose.

In the present improvement the entire working mechanism for operating the nee dle, looper and feeding device is so arranged as to provide a clear space underneath the machine for the positioning of the work so that a bag may be filled to its full capacity leaving just a short margin at the top of the bag so that such top portion may be drawn together and stitched while it is fed to and from the machine by mechanical means. i v y The object of the invention therefore is the provision of an improved sewing machine of the class referredto, comparatively simple and reliable in its operation and by means of which the work to be done can be more readily and quickly accomplished.

A further object of the invention is the provision of an improved feed device operating mechanism. 4

In the drawings accompanying and forming part of this specification, Figurelis an end view of the machine; Fig. 2 is a bottom View of the machine shown in Fig. 1; Fig. 3 is a side view of the machine shown in Fig. 2 with the arm broken away on the line 22; Fig. 4 is a sectional view of the bottom plate, taken on the line 11, Fig. 2, and looking in the direction of the arrow; Fig. 5 is a detail perspective view of the feed mechanism; Fig. 6 is a detail of the throat plate; and Fig. 7 is a view partly in section of the actuating means for the feed bar.

Similar characters of reference indicate corresponding parts throughout the several figures of the drawings.

The main supporting plate 1 of the machine carries suitable bearings 3 and 4 for the vertically supported main driving shaft 2. Carried by the plate 1 is a laterally extending overhanging arm. 5, the outer part 6 thereof carrying at its lower end the needle bar 8 carried by bearings 7, the presser foot bar '9, and the guide bar 10, all of which are supported by suitable bearings.

The guide bar 10 and presser foot bar 9 are connected by a cross-member 12 clamped thereto, and this guide bar 10 reciprocates in its bearings 11. A spring 13 rests thereon to give pressure to these bars and a screw '14 serves to regulate the tension thereof.

A presser foot lifting collar 15 is also.

clamped to the bar 9 to co-act with the hand lifter 16 which is pivoted at 17 to the Inachine frame. A. presser foot'l9 is pivoted at 20 to its shank 18 which is secured to the bar 9. This foot has a portion 21 and an out-turned extending end 22. The main shaft 2 carries a belt wheel 23 and an eccentric 23 which operates a connection 24, the opposite end 25 of which is formed to embrace a ball stud carried by the needle lever 26 which lever is pivoted at 27 to the arm 5, and actuates the link 28 pivotally secured thereto at 29, and the other end of which link is pivoted at 30 to the needle bar clamp collar 31 for the purpose of reciprocating the needle 32 which is suitably clamped in its bar. This needle lever 26 has an extending end 34, having pivotally connected thereto at 35 a looper actuated rod 36, the other end of which is pivoted at 37 to the looper driver 38 to rock or reciprocate the ried by the looper shaft 44. A reduced end of the looper shaft extends into this yoke hub 47 and the end motion of the yoke on the shaft is controlled by the nuts 48.

From the foregoing it will be seen that rotation of the wheel 23 and main shaft 2 reciprocates the connection 24 and thereby the needle lever 26 to reciprocate the needle and looper while at the same time the other eccentric 45 is so timed as to reciprocate the looper shaft 44 so as to move the looper end 49 seated in the shaft 44 and thus rock it on its pivot 40 so as to move the looper from the rear of the needle where it takes the needle loop to the front thereof where it presents the looper loop' to the needle, completing the stitch. This mechanism is similar to that described in Weis Patents Nos. 933,407 and 990,414. The needle thread is handled in the usual manner, common to this type of machine. The looper thread is also handled and controlled by a pull-off, takeup and nipping mechanism 50 similar to that shown in the patent to Weis No. 933,408, and therefore a detailed description of this mechanism is unnecessary.

The feeding mechanism is controlled by the hand wheel connection 24 which is provided with an extending lug 51 carrying a ball stud 52, see Fig. 7, clamped therein by a nut 53. The ball of this stud operates in a socket 54 of the feed bar 55, which extends from one end of the machine to the other, and in substantial parallelism with the driving shaft. The ball stud 52 may be provided with a ring 52' to fit in the socket 54 which would give a larger bearing contact and longer life. To properly guide this improved form of feed bar a double forked yoke 57 is provided and the feed bar moves in one forked end 56 thereof. is pivotally secured to the machine plate 1 by a pivot screw 58 having a nut 59 thereon. This yoke is also provided with a forked end 61 bored to receive a pivot pin 62 for supporting the feed bar 55. This pin is secured in the feed bar by means of a screw 63, see Fig. 5. The feed bar terminatesl in an extension 64 cut out to receive a feed dog or device 65 which is segmental in shape to conform with the are that the bar 55 and the yoke 57 swings in by reason of the pivot screw 58. As the wheel. 23 and eccentric 23 rotate, a lifting motion is given to the ball stud 52 and the end of the feed bar 55 so that it moves in the forked end 56 and is guided thereby. Simultaneously with this lifting motion, the connection 24'moves laterally swinging the bar 55 and its yoke 57 on its stud 58, and

the reversal of these movements thus gives a four motion to the feed dog, and this motlon is substantially the same as-that glven by the usual two eccentrics, where one This yoke is used to reciprocate the feed laterally and w the other is used to reciprocate it vertically. In the type of machine shown, it is desirable to have a fixed feed stroke .so as to give a positive feeding action on all classes of work to insure a uniform length of stitch. The feeding mechanism must be entirely out of the'path of the contents of the bag and the device described has been found very satisfactory for'this work because of the long leverage of the feed bar and the circular motion thereof as this tends to lift the loose end A of the filled bag B, see Fig. 1. From the foregoing it will be observed that the feeding mechanism in the present improvement is so connected as to obtain all of its feeding movements from the needle driving means at the upper end of the machine. In other words, the hand wheel connection or eccentric which reciprocates the needle lever and the needle bar and also the looper bar also operates the feed bar in such manner as to give the feed dog a circular feeding movement and also a rise and fall movement, so that when the bags to be stitched are led into the machine the feeding motion is such that it tends to lift the loose or free edges of the bag vertically so as to stitch same across the top in a uniform manner. And'so far as I am aware, I am the first to provide a bag machine in which the feed operating bar is so located and connected that its operation will tend to lift the free or loose edge of the bag to be sewed in a vertical direction.

In order to handle the filled bags with ease and rapidity it is essential to have the end of the machine carrying the stitching mechanism of peculiar shape to form a bag neck receiving opening or mouthportion, and therefore I have provided the presser foot with a turned out part as 22 practically conforming to the inclined front edge 68 of a bottom plate 69, see Fig. 2. TlllS plate 69 is arranged to support the throat plate 67 which is secured thereto by screws 70, and cut out as at 71 and 72, see Fig. 2', to prevent the dirt from interfering with the operating mechanism as on thls class of work the filling material used in the bags is apt to deposit in the machine and cause undue wear of the mechanism. The cut out portion 71 also permits the looper 39 to operate therethrough. As the machine operates rapidly every facility must be provided so that the bags can be fed into the sewing machine With case. It is for this reason that an extended presser foot and a peculiar shaped bottom plate is provided so as to present a free opening at C, see Fig. 2, to readily take the bag with little guidance and hold it in the position shown by dotted lines at A, Fig. 1, while it is stitched across the top. Simultaneously with this operation a stock tag is-often stitched in with the bag, and this must be presented to the machine by the attendant as the bag is being stitahed. A needle guard 73 is located at one side of the needle and is secured to the bottom plate 69 as at 74, and it has'a suitable adjustment to suit the various sizes of needles used. At the rear of the bottom plate 69 is secured a cutting blade 75, see Figs. 2 and 8, which cooperates with a swinging blade 7 6 pivoted at 77 to a hub 78 and actuated by a link 79 pivotally connected at 80 to the blade and at 82 to an actuating lever 81. to the machine support at 84 and extends as at 85 outward and carries a pad 86 in position to be actuated by the hand of the operator for the purpose of bringing the knives to a position to sever the chain of stitching after each bag is sewed. Surrounding the pivot 8 1 is a coil spring 89, see Fig. 1, having one end entering a hub 90 and the other end entering an adjustable collar 91 held in position by a nut 93.

This machine is intended for use in con-' nection with the apparatus described in Patents Nos. 92%,175, 918,184, 973,123, and 1,009,165, to J. E. Miller, wherein a con veyer is used to bring the bags of various sizes up tothe sewing machine for the purpose of closing the mouths by sewing, in which the apparatus is designed to handle bags of varying sizes, at times alternating with one another, and comprises means of adjusting the conveyer instantly for the various sizes of bags to present them to the sewing machine for the proper stitching. The operation of the conveying mechanism of the sewing machine, the presentation of the bag mouths to the stitching mechanism, the starting and stopping of the sewing machine, and the cutting of the threads after the bags havev been sewn, may all be taken care of by one attendant.

In order to cover. the entire working mechanism and protect the operator from the same, I have provided a swing cover plate 100, shown in section inFig. 1 and in an open position in Fig. 3. A portion of this plate 101 overhangsj he takeup mecha nism, and a portion 102 covers the main shaft and a part of the feed and looper mechanism. A pin 103 cooperates with a swinging latch 10% to hold the cover plate when in a closed position. The cover plate is hinged in position as at 105 and can be swung out of position as shown in Fig. 3 to give free access to the mo ving parts for thepurpose of threading, etc'."

From the foregoing it will be observed that the looper and feeding mechanisms are all locatedin a comparatively small space and within the casing formed by the main supporting or side plate, the bottomplate 'and the hinged cover, whereby they are protected from dirt and contents of the filled This lever 81 is pivoted bags, and that the feed bar extends from one end, as the lower end of the machine, to the opposite, or upper, end of the machine, at which latter point it is connected with the driving shaft by means of which it is operated, so that the driving means for this feed bar is entirely away from the stitching mechanism.

It will be understood that the various details may be more or less modified without departing from the spirit or scope of the present improvement.
